PAPER-FILE.

Application filed November 25, 1907.

To all whom t may concern Be it known that PHILIP H. YAwuaN. of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Paper- Files; and l do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying` drawings, forming a part of this specification. and to the reference-numerals marked thereon.

My presentinvention relates to Ipaper tiles, and particularly to the type employing a pair of posts upon which vthe sheets are impaled and a pair of cooperating members, usually in the form of an arch, movable si multaneously relatively thereto and upon which the upper sheets are transferred to render the lower ones accessible, and my invention has for its object tov provide an improved tension device for the movable arches which will operate to retain them in or out of engagement with the posts when moved to either of these positions by the operator.

My improvements are further directed toward the construction and arrangement of the .coperating `parts of. the posts and arches: i

To these and other ends` this invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the ,claims at the end of the specification.

In the drawings: Figure l is a top plan view of a paper file embodying` my invention. Fig. 2 'is a side elevation thereof. Fig.l 3 is a bottom view of the device with the cover plate removed. Fig. 4 is a vertical section through the impaling, posts talen`on the line 4 1 of Figa l, and Fig. 5 1s vertical central section on the line 5--5 of Eig. 1.

Similar reference numerals in the several figures indicate similar parts.

In't'he device illustrated l indicates a .base member provided with an eye 2 by means of which it may be hung upon a nail or hook and which is usually secured at the end of a board or backing by screws extending through the' apertures 3, for which Areason the bottom is preferably made fiat, and the whole may be conveniently constructed by casting, 0n its under side the base is pro- Specification. of Letters Patent.

vided with a recess or chamber 4 covered by a plate eiigagii'ig against. lugs G and held in position flush with the bottom of the base by a screw T threaded into a lug S within the chamber. The impaling posts l) are preferably constructed of tubular stoel; and extend perpcndiculartv to the hase or backing and parallel to Icach other at a suitable distance apart, according to the size of the papers lo be accommodated. Their lower ends pass through the base and are secured hy the expanded portions l0 on either side, while their upper ends are eut obliquely to form lateral o'iei'iings ll (in the present instance upon opposite sides). lpposite said openings and communicating therewith arc arranged lrai'isversely extending apertures l2 in the wall of thc tubes at the ends ofthe posts. The arches 1,23 arejourualed in bosses 'llt in the base member and also preferably in the cover plate 5, as at l5, to extend within the chamber 4 and to rotate upon axes parallel with the impaling posts and, in the present instance, to each other. They are preferably madcof wire and their free ends are reduced eccentrically at lo, as shown in Figs. 2 and al, so as to engage and be accommodated within the openings ll and at the same time provide shoulders 17 to effectually cover the points 18 of the posts, which if allowed to project, would engage the papers while being slipped from 4the arches thereon. By engagement with these shoulders, the ends of the posts also serve to supportthe arches when downward pressure is applied thereto. and prevent them from being bent out of alinemcnt. In my construction thi` one member thus forms a substantial continuation of thevother and in order to preserve the rigidity of the connection l provide the ends of the arches with lateral projections in the fo-rm of pins 19 which engage within the apertures l2, and which may be conveniently punched par.- tially out from the material of thc-member. 'lhi lower ends of thc arches being journaled'in the cover plate, as well as extending through a reinforced port-ion of the base, afford an extended bearing and promote a uniform movement that will bring the co'- operating` devices at the free ends always 3 accommodated within the chamber, 20

' desires to attach forming parts thereof are plates 20 to which are pivoted the opposite ends of a rod 21 connecting the arches for simultaneous movement in opposite directions, it being desirable that they move apart rather than toward each other for purposes of convenience. Likewise pivoted to each arch,'

throughthe medium of the plates, at points normally lying upon the same side` of the plane of their axes is a tension member 22 which in the present instance i's under com-A pression and normally retains'the arches in yielding engagement with the posts. I pre-A fer to form this tension member from `a spring wire looped or bent, as shown, at one or more points transversely to its general extent and having all its parts in the same plane, whereby it is rendered flat and easily allowing the latter to be made shallow to reduce the general bulk of the device asa whole. The eleasticity of these looped portions provides ample energy and when the operator or remove a paper he simply grasps one of the arches and rotates it away from the post, the other moving cor respondingly and flexing the spring as its` points ofiattachment are moving in opposite directions. As soon as these points of attachment have moved beyond the dead center, that is, to the opposite side of the plane of the axes, the said member or spring will continue the movement until one of the plates engages one ofthe lugs 6 on the base' as a limit, as shownin dotted lines in Fig. 3. The arches will then beretained in such open position until moved back by the operator and the posts will be'free and accessible.

-I claim' as my invention:

l. In a paper file, the combination with abase member and an impaling post mounted thereon having a lateral opening at its upper end and an aperture arranged opposite said opening, of an arch rotatably mounted on the base to move upon an aXi parallel to the post and having its free end arranged to engage within the opening in the latter, said outerend being provided with a lateral prolection removed from the extremity' thereof and coperating with the aperture in the post,the extremity of the archjbeyond the projection havinga lateral bearing against the post.

2. In a paper file, the combination with a base member and an impaling post mounted thereon provided with a lateral opening near its upper end the upper edges of the walls of said opening'being terminated in a plane ysaid end engaging over Awithin the opening in oblique to the post to form an point, o an arch rotatably mounted .on the axis parallel .to` the base to move upon an its free end Withpost into engagement at in the opening in thev latter, with a square overhanging shoulder adjacent of the post.

3. In a paper tile, the combination with a base member and an impaling post mounted thereon having a lateral opening at its upper end of an arch rotatably mounted on the base to move upon an laxis parallel to the post and having itsfree end reduced lto constitute an eccentric projection engaging the latter, and forming a shoulder covering -the upper end of thel wall of the opening.

4. In a paper file, the combination with a. base member and a pair of impaling posts mounted thereon, of a pair'of arches rotatably mounted on the base to coperate withv the impaling posts and connected for'simulfs taneous movement, connected to both a-rches at points both of which normally lie on the samesideof the plane defined by the axes of rotation of the arches and are removed ror spaced from the said axes to rotate about the latter.

and provided the impaling point and atension member 'r I 5. In a paper le, the combination with a base member and a. pair yof impaling posts mounted thereon, of a'pair of arches connected for simultaneous movement, rotatably mountedon thebase to coperate with the J impaling posts and having their movement in one direction limited by engagement with saidv posts, a plate secured to one of the arches, a stop on the base adapted to be engaged by said plate for limiting the movements of the arches in the other direction and means pivotally interlocked4 with both arches at points removed from their axes of Arotation for exerting a tension thereon.

6. In a paper file, the combination with a baseymember and a, pair of impaling posts mounted thereon, of a pair of arches rotatably mounted on the base to coperate with' the impaling posts and connected for simultaneous movement, and a tension member pivotally connected to .removed from their axes of vrotation the said points being located uponone side of the plane of the axes of the arches when the latter are'closed against the posts and upon the other side when they are open.
